Posted on May 17, 2011 at 15:09 Hello AlexDion, Am also having a similar problem. I want to set registers of STM8L152C6 as follows and that is the syntax I am using. But the registers are not get assigned.TIM4_PSCR = 0x0A; TIM4_CR1 = 0x01; TIM4_IER = 0x01; When debug values are not assign to registers. Have you got any idea on this issue? Any suggestions regarding this matter is appreciated. Thank you.
